I. TAG QUESTION (CÂU HỎI ĐUÔI) 

1. Quy tắc chung:

- Câu nói và phần đuôi luôn ở dạng đối nhau

Câu nói khẳng định, đuôi phủ định?

Câu nói phủ định, đuôi khẳng định?

Ví dụ:

          The children are playing in the yard, aren’t they?

          They can’t swim, can they?

•  Câu giới thiệu dùng “I am”, câu hỏi đuôi là “aren’t I”

Ví dụ:      

         I am a student, aren’t I?

• Câu giới thiệu dùng Let’s, câu hỏi đuôi là “Shall we”

Ví dụ:    

         Let’s go for a picnic, shall we?

•  Chủ ngữ là những đại từ bất định “Everyone, someone, anyone, no one, nobody…” câu hỏi đuôi là “they”

Ví dụ:     

           Somebody wanted a drink, didn’t they?

           Nobody phoned, did they?

• Chủ ngữ là “nothing” thì câu hỏi đuôi dùng “it”. Và Nothing là chủ ngữ có nghĩa là mệnh đề giới thiệu đang ở dạng phủ định, câu hỏi đuôi sẽ ở dạng khẳng định.

Ví dụ:  

          Nothing can happen, can it?

•  Trong câu có các trạng từ phủ định và bán phủ định như: never, seldom, hardly, scarely, little… thì câu đó được xem như là câu phủ định – phần hỏi đuôi sẽ ở dạng khẳng định

Ví dụ:     

          He seldom drinks wine, does he?

• Câu đầu có It seems that + mệnh đề, lấy mệnh đề làm câu hỏi đuôi

Ví dụ:    

          It seems that you are right, aren’t you ?

• Chủ từ là mệnh đề danh từ, dùng “it” trong câu hỏi đuôi

Ví dụ:               

          What you have said is wrong, isn’t it ?

          Why he killed himself seems a secret, doesn’t it ?

• Sau câu mệnh lệnh cách (Do…/Don’t do v.v… ),  câu hỏi đuôi thường là … will you?:

Ví dụ:               

         Open the door, will you?

         Don’t be late, will you?

• Câu đầu là I WISH, dùng MAY trong câu hỏi đuôi

Ví dụ:      
                        I wish to study English, may I ?

• Câu đầu có MUST, must có nhiều cách dùng cho nên tùy theo cách dùng mà sẽ có câu hỏi đuôi khác nhau

Must chỉ sự cần thiết: => dùng needn’t

Ví dụ:    

          They must study hard, needn’t they?

• Câu cảm han, lấy danh từ trong câu đổi thành đại từ, [ ] dùng is, am, are

Ví dụ:             

         What a beautiful dress, isn’t it?

         How intelligent you are, aren’t you?

• Câu đầu có I + các động từ sau: think, believe, suppose, figure, assume, fancy, imagine, reckon, expect, seem, feel + mệnh đề phụ, lấy mệnh đề phụ làm câu hỏi đuôi.

Ví dụ:             

          I think he will come here, won’t he?

          I don’t believe Mary can do it, can she?

II. COMPARISONS OF QUANTIFIERS (SO SÁNH ĐỊNH LƯỢNG)

1. Công thức so sánh định lượng:

2. Cách dùng

•  More : thêm,nữa, nhiều hơn

Ví dụ:

          I have more books than she.

          (Tôi có nhiều sách hơn cô ấy.) 

•  Less: ít hơn, kém hơn. ;less dùng với danh từ không đếm được.

Ví dụ:

          Their job allows them less freedom than ours does. 

         (Công việc của họ làm họ có ít sự tự do hơn chúng tôi.)

• Fewer:  ít hơn, kém hơn. Fewer được dùng với danh từ đếm được

III. Read the text carefully, and then answer the question below.

Mumbai, which is located in the western coast of India, is the capital of Maharashtra state. It is home to Bollywood, the centre of Hindu movie industry, and the film “Slumdog Millionaire” was based there. Poor people have to live in slums. In the slum, people have to live with many problems. People have to go to the toilets in the streets and there are open sewers. Children play among sewage wastes and doctors deal with 4,000 cases of death a day because of lack of hygiene.

Next to the open sewers are water pipes which can crack and take in sewage. Dharavi slum is based around this area. There are toxic wastes in the slum including hugely dangerous heavy metals. Dharavi is made of 12 different neighbourhoods and there are no maps or road signs. The further you walk into Dharavi from the edge, the more crowded area becomes. People live in very small slums, often with many members of their extended families.

1. Where are the toilets in the slum?

2. Where is Mumbai?

3. Is Mumbai famous for the film industry? Why or why not?

4. How many neighbourhoods are there in Dharavi?

5. What happens to water pipes in Dharavi?

______________________________________________________

IV. Read and decide if each statement is true or false or not given.

OVERPOPULATION (CONT)

These two problems are related, but they happen in different parts of the world. Overpopulation tends to be a worse problem in poorer countries where people rely more on farming and often have larger families to help with the workload. Overconsumption is a much worse problem in the richest countries in the world. The reason for this is simple. When people have more money, they use more resources. For example, look at carbon Missions. This is the amount of carbon released into the atmosphere based on the energy people use by doing things like driving a car, riding in an airplane, or heating a house. The carbon emissions of one American today are roughly equal to those of four Chinese, 20 Indians, or 250 Ethiopians. It is basic math that if the rich continue to use the earth’s resources at this pace, one day those resources will run out.

IV. Write a short paragraph about the population change in Ho Chi Minh city over the past 30 years, using the cues given.

Ho Chi Minh City is the largest city in Viet Nam. In 1979, there were only 3.4 million and in 10 years later the population of the city was only about 4 million because the economy did not develop much. However, thanks to the Renovation policy starting in 1989, in the next decade there was a dramatic increase in population, and the figure reached over 5 million. With economic growth, the living standard in Ho Chi Minh City is higher than that in other regions, so many people came to this city to look for jobs. As a result, Ho Chi Minh is the biggest city in Viet Nam with a population of over 7 million in 2009, and now about 8 million.
